Excellent questions.
It’s instructive for all of us to know, that we do not have a constitutional right to vote in a presidential election.
States are allowed to choose electors to the electoral college at their discretion. They are not required to choose electors via a popular vote.
If a state votes Republican in the popular vote in a state, but a Democrat wins the nationwide popular vote, and that state had decided to award electoral votes that way, I’m not sure legally there is anything anyone can do to change that.
Since states are empowered to choose electors, and are not required to even hold a popular vote election, it’s hard to see how state voters in a state could claim to be disenfranchised, when there is no constitutional right to vote for president in the first place.
